Hi Derek and Terry. Just saw your advert in The C.C. Magazine, and it reminded me to write. Well after about 8 months of use on our new T/A van, I am pleased to confirm that the Lock n Level Combo has performed well, as advertised, having been used more than a dozen times, in the UK and abroad on some really rough hard standings, as well as grass. This really is a brilliant piece of kit, that came just in the nic of time, as I was dreading levelling and locking the van with jack and boards having never had a T/A before but watched others struggle. You have really enhanced the very pleasant experience, which is T/A caravanning.
